Protocol Integrity

Definition ∞ Protocol integrity refers to the trustworthiness and security of the underlying rules and code governing a blockchain network. It signifies that the protocol functions as intended, without vulnerabilities that could be exploited to compromise its operation or the assets it manages. Maintaining protocol integrity is paramount for user confidence and the overall stability of the ecosystem. Audits and formal verification are common methods employed to ascertain this integrity. Context ∞ Protocol integrity is a constant concern within the cryptocurrency space, especially following incidents of smart contract exploits or network failures. Discussions frequently center on the robustness of consensus mechanisms, the security of codebases, and the efficacy of upgrade processes. Assurance of protocol integrity is foundational for adoption and sustained value.
